You know, you really shouldn't put fake NPCs in your story because someone will confuse it with something. If you use any greek letters at all, everybody will think that you're actually referring to every organization that actually exists. Because you know, people are really stupid. You should just give the organizations names like "Butterball" or "Squid" -- oh, but then someone will confuse them with Farmhouse or Fiji or something. Maybe you should rethink the whole story idea. I mean, if you make up anything about a fake sorority, people will thing that ALL sororities are just like that one and that we ALL engage in the behavior of your characters, which may or may not be questionable, but really you should try to avoid it. I mean, people can't tell the difference between fiction and reality. Maybe you could invent an entire alphabet that has nothing in common with any letters that actually exist, and use them to name your organizations, just to be extra sure that nobody is ever confused. I mean, some people may still be confused, but at least it won't be as many people as if you used real, actual greek letters. Because you know, people are really stupid.
